Application filed February 12, 192'?. Seriall No. 167,749.

The invention relates to a machine adapted for combination with and atthe side o'l a binder and has gear means driven from the bull wheel ofthe binder for various power uses.y life furnish a traveling conveyormeans in combination with Aa curved trough element for receiving,passing and turning bundles and means tor casting the bundles against anabutting plate as a straight edge tor lining up the bases ot thebundles; shock former and clamping means associated therewith forsupporting bundles,` thence lclamping and dropping` the clampedv bundlesto a ground position, thence effecting the release ot the clamping meanswithout disturbing the set ot the shocked bundles. Vile form the shockas an oval rather` than as a round shock, this arranges the bundles soas to permit an air passage lengthwise through the shock which assistsin curing the grain straw. Vie employ a caster wheel to support theweight ot the shocking mechanism. The elevating mechanism is carriedtrom the binder inde pendently from the trailer.

` The invention is similar in purpose to that disclosed in our penningapplication `for Letters Patent, Serial No. 114,195, iiled dune 7, 1926.ln the present invention we have provided an entirely novel method ot'reversing the bundles and for positioningl them against the straightedge abutting board. Also various in'iprovemcnts have been made to theprior described shock 'forming mechanisms. l The effect of aligning thebutts ot the bundles against the abutting board, the compact arrangementot the bundles one upon the other in the shock Jrorming means expanded,thence the clainging oi the shock forming means with av torceinciden-tal tothe dropping while compacted and the later release of theshock is claimed. y

In Figs. 1. and 2; the bull wheel 20 oit a `grain binder is providedwith the axle 25; at 2l, 22, 23 and 24 are seen trame elements ot thebinder. From a sprocket on the bull wheel the chain 2G drives a sprocketrigid to the shatt- 27 carrying a bevel gear 28 which meshes with thebevel. gear on the pitlnan shaft 29. A split. sprocket 8O is rigidlyclamped to the pitman shaft 29 to enable us to secure power trom thebinder wheel 2O for operating o ur auxiliary machinery. A chain 3ldriven from sprocket 30 leads around and drives the sprocket 32 rigid toshaft 35. Frame members 83 attached to the binder trame support bearings34 tor the shaft 85. A bevel `@fear 36 on shaft 35 meshes with the bevel47 on shaft 46. At 37 in the member 33 is a bearin,. g` for the shaft46. At 88 is a tubular housing' and at the outer end at 39 a bearing isshown tor the shaft 46, or so th at the shat't 46 is axially arrangedwithin the housing 38. At 40, 41. 42, 42", 42y and 43 are seen braceelements leading;l from binder 'frame elements to outer supporting rionsrelative to the rsihalit rlhe brace 44 leads :trom the members and 43 tothe bearing;v 39 as a support. it 45 is a. bearing for the outer end oitshaft 46. The .inner end ot shaft 46 carries the driven gear 47. Al-:eyway 48 is provided. on the outer portion oit the shaft 4G.

At 4S) i seen a easter wheel. rotating, on the shaft 50 supporting theupright side members 5l and at 52 is a pivotable bearingl lor the sidemembers 5l. A pair ot arms 5?) and 54 attach at 55 and 56 to the tubularhousing' 38 as later explained. ylhe members 5?) and 54 connect at theirouter ends to the upright trame elements 57 and 58. respectively. Themember extends down for control. lever taeluneuts later euiilained.Paired herb Zontal members 59 and 60 are the outer side elements of thetrame supported by the caster wheel 49, these members attach rifidly tothe members 57 and 58. And at Si is seen one of the lower pair of tramemembers connecting to a member 59 by the frame member 62. Braces 53 and53b connect from trame 53 to sprocket shifter 53C.

At G3 is a side board element for the bun die conveying` mechanism 64,which is canvas conveyor belting if desired or simply a pair o1 chainside elements connected by transverse slats 66 carrying spikes 65. Sidemembers 67 tor the conveyor are of lll-shaped conliguration and areiitted with angle elements such as GS and 69 as guides as well asstitfening' members. At. 70 is a metallic trough like element rigid tothe sides 67-67. A sprocket 7l is keyed to the shaft 46y and carries achain 72 to drive the sprocket 73 rigid to shaft 74 at the upper end ofthe conveyor. This shaft 74 is extra long so the assemblage can beadjusted and then iiXedly fastened 'from the binder or so that the board63 is at a proper spaced distance 'from the binder deck or that thegrain bundles dropped from the binder deck will tall upon the conveyor64 as in Fig. 10. The angles 68 and (39 furnish gruicline` means forthey chains G4 et the conveyor. The board 63 projects within thebellshaped lower end ot the trough 70. A bearing); 7 5 carried by thebrace 7G supported by the trame 67 houses the shaft 74. Bearings 77 and7 8 adjacent the sides 67 also house the shaft 74. At 79 are seensprockets rigid to shaft 7 4 and a roller 8O for driving` the conveyor64. At the lower end of' the conveyor 64 is shat't 8l earryinga rollernot shown While sprockets 82 carry the chains (34. The driven shatt 46thus drives the conveyor 64 in its lJ-shaped carriage or so as toreceiif'e a bundle in 10 carry it in the direction of the arrow to thetunnel 7 O thence upwardly intermediate the tunnel and con-A veyor G4Fie: 4 the butt ot the bundle going y upwardly and it will thus be seenthat the ll-shaped assembly turns or reverses the posi tion ot thebundle so that as it .nears the top oit the curved carriage the buttfaces towards the rear. As in Fia'. 4 the thickness ot the bundle isaccomu'lodated by the yieldingr oit the conveyor G4 to the dottedposition 64x. The upper end oit the carriage lies in a horizontalarrangement as seen in Fig. l as the side 67X. The trough 70teri'ninates in the Vdat plate 83 ending at the point 83X. lh,- low themember S3 is another men'iber 84 spaeed apart to torm a rectangularpocket a nd within which the slidable floor element 85 is lpoeketed. y

ll`if3f. 6 shows a roller element having diselike ends 86, collars rigidat 87 to the shatt 8S as spacers tor the rollers 86. It will be seenthat intermediate the disc ends ot the rollers are tormed a plurality oftransverse ribs 89 and it will be seen that these ribs are deeper .nextthe discs than at the center or so that a bundle passing` butt end firstrearwardly oil1 ot the floor 83 will tend to center or ride intermediatethe discs 86. The shaft. 88 is adjustably and slida-bly mounted insupports 907 which compose a Ushapcd element bolted to an element 91which is rigid to the vfloor element and is downwardly bent therefromand as a part thereof. A pair of braces 92- oi L-shaped character. areattached to the respective side members 67 asV at 93-93. Also a pairv ofbraces 9st attach as at 93X and 3y to the braces 92 and side elen'ients07. Also braces and are provided on. either side of the members 07 andare attached as at 93W and 9532 to. such braces rlhe braces 92 and94rserve to strengtliicn the conveyor carriage mechanism as will bereadily understood. rlhe ln'aces 95 and 95X are for differei'it purpose.

Referring to Fig. 5 isa seen a. telescopic bundle chute combinationcomposed ot a'flaring troughdike outer sheet metal chute element 96which has a pair of lugrs 9? rigid thereto and to which a bar 98pivolally connects. rl `he element is rigid with the element. 99 whichforms an ang-le therewith seen and the composite lever .98-99 is rigidlyattached to the shaft 100 rockin ings in the braces 95. lt will be unthat the member 98 is forked l eyond the section` taken in Fig. 5 so asto attach to the shat't 100 on either side of the members 07, thus thereare two members also. To each member 99 pivot-ally linked a meniber 102as at 101 and which pivotally connects at 103 with another member 105which rocks on a support 101 carried bythe brace 95X. Th forked brace10? pivotally conn cts to the lugsupports 108 on rear element 91, andeac i outer end oi the brace 107 pivetally connects as at 106 to therocking element 105. The inner chute 109. telescopically tits the chuteThe edge 110 of chute 96 is bent around the edge 111 oi chute 109, theedge 111 is reinforced by a rod 112. Movements ot shaft 100 cause levermovements of the train oi clen ments 99-107 inclusive to vary therelationship` ot' the pa 90 and 109 with respect to xach other as seenin Figs. 1 and 3 'for purposes later e): Jlained. A hood 113 Fie', 5 hasan edge element 114 composed of a bar of yLl-shaped character7 each legtl'iereo't' toi-mine a lever 115 and arranged to pivot as at 110 onelements carried irom the sides 071". A cable 117' leads. Yfrom the leve115 to 'the driver of the binder so that he may when desired pivot thehood 11S-l to the dotted pesition 113x. The stop 119 serres as a rest.for the edge bar member 111. it 119 is a stop board carried by the endportion of the hood 113. 'lhc 'loot lever 120 near the driver of thebinder enables him to rock the shaft 121 provided with an arm 122 linkedby a member 123 to arm 124 to rock shaft 100'.` A friction element 125acts as a brake to enable the shaft 100 to be stopped and held at anyposition.

117W and 117Z are bearings on the i'rame 1171' as seen. A tensionspring` 133 connects trom of the binder.

The bundle carried by the conveyor` 641 `5 closing` the chiite.

the paddle roller 89 into the chute 109 and 100 has actuated the leversystem 98-107 toy draw backwardly the enter chuter element 96 and toprojectv the loor memberl 85 rearwardly. The lever 117X released droppedthe hoodf113 tothe stop position 118 and. the stopboard 119 dropped tothe position seen in Fig'. rlhe bundles drop oil' the stop board 119stops them. By shitting the roller 89 in either direction by the drivermoving,` the rod 8,8, the bundles can be shiit'ted to either side or"the chute 109V as it fills. The springs 120 intermediate stops 9,0 androd elements 127A and 128 normally position the roller in a centralizedrelationship to the chute 109 unl-ess otherwise desired. The shat't 100can be actuated again to reposition the chiite as it fills or so thatbundles can be dropped upon lower bundles. The incomingl bundlesstriking` paddles S9 help to settle lower e mies by causing the paddlerotation to strike the upper ends ot' the lower bimdles. The foregoingarrangement of the closure of the el'iute 109 by board 119 is necessaryduring the time interval of setting. a shock. As soon as the shock hasbeen set and the abutting board and shocking mechanism, later described,have been returned to the position illustrated in Fig. 3 then the`shaft` 100 is shifted to lower the outer chute 9G to its limit and'todraw rearwardly the door 85 within the pocket. The. hood is raised tothe ldotted position 113X and the bundles previously collected in theclosed chute assembly 109-119 are permitted to fall orslide downthe.chute 109-95 when they are caught within the shoekformcr and stopped andaligned by the abutting; board. Each other bundle carried upwardly bythe conveyor in the curved trough 70 isy thus cast ott' the lower` endkoft the chute 90 against the abutting` board. When there have beensutlicient vbundles passed to the shocktormer to make a desired shock,then the driver airain stops on the pedal 120 and operates thelever11?'X to bring' the yhood and parts 90-109 to the prior positiondescribcdas of Fig. 1. The bundles to lo-m the shock are, deposited'trom their supper ed position. on., the` abutting; board andshocktornjier seen in Fig. L to the shocked position seen in Fin'. 1 andby the means and methods next described.

Upright braces 129 carried trom trame element-s 59 and 6.0 bendrearwardly as at 129X as the post supports for the pivotable armelements 130 of the abutting board 131 which is rigidly ai'lixedthereto.

The shock former parts in Fig. 8 have filled with a suitable number ot bundles to make a shock. The driver ot the binder prevents more bundlesdropping?,` therein by shiifting` the chute assembly `to the positionseen in 1 and 5 which stops bundles from reaching the shocker until ithas had time to be lowered and set a shock and be again returned to theposition Fig'. 8,- wlien the bundles would be permitted to tall Yfromthe stop board 119, aga inst the abutting board 181 and within the .Achain 280 driven shocker arm elements. Vhile the position seen in Fig. 5was maintained, the arms 85 and 188 Figs. 8 and 8 wjer'e caused toassume the position seen in Figs. 7, and 8A, this was done by shittinglever 217 to draw Jfork 228X against the hub 289 ot' drum 287 wherebydrum 287 engaged by clutch 284 wound up cable 181, the latch connection1904492 was broken, the bars 198 and 194 move towards the ends 17 0 ofhook arms 169 lateh'ed at 167. r1`he squeeze otarins 185 and 186 andallied 'orn'ier `parts has been -accon'iplished just as clamp 218xstrikes the plunger 242 and the wedge 245 kieks the fork 228 back toneutral. rlhe hooks 109 being also disengaged the cable 215 unwinds fromthe drum, as the weight ot the shock and shocker together with vthe pullon cable 181 has caused the shock to lower towardre; the ground, therods 184 have shoved the abutting board up to the position seen in F ig.1 out ot way ot the descending shock. The ground spike is driven intothe ground a distance and the runners 257 de'- pen'ding trom the underside ofthe trame 178 strike the ground at the same instant as the buttso-i" the `composite shocked bundles as clamped in Fig. 7. it this point`the latch arm 202 carrying the hook 208 which in Figs. 7 `and 9 hasbeen engaging the bar 198 to maintain the clamped position illustratedis lifted to the dottedposition 208x. The releasey ot the hook 208 isetl'ected by thetrip rod 204 striking;` the ground at its outer ends.The trip rod supported in the bearings 204x and the latch 202 is rigidto the trip rod hence the hook tends to drop over the bar 198 exceptwhen the action oi the ends strikingthe ground aiiects the release. Themovement or the binder constantly torwardly, the ground spike staysiiXed inthe ground or so that the 'trame 178 travellingi also forwardly,the bars 195', 197 and 198 operate to swine' open to the position Iseenyin Fig'. 8 thus releasinnv the shocked bundles throifinb the rearopening' betweenthe expanded forked elements 212'-218. l/Vhen therunners 257 have traveled forwardly far enough, then the ground spiketends to lift out ot the ground, that is it must also travel torivardlythrough the rontportion of the shock, the canvas 214 has held a gapspacing the width ot the spike between. the bundles to permit the spiketo pass out, then the bundles close together as the shookl furthersettles into place. rlhe lever is shifted-again to move drum 286 toengage clutch 285 to wind up cable 215 to draw the levers 148 and 144forwardly at which time the curved parts 151 and 152 n'iovinp; throughthe elevises 155 give a rapid and quick movement to yank the abutting`board down behind the raised shock former or seen in Fig. 8. lThe hooks169 engage with the elements 157-156 and the shock former is open as inFig'. 8 to permit the board 119 to be raised and bundles to dropbetweenthe arms of the shock former. Again the stop 216 reaches the hole 250 inthe plunger 248 and the wedge 244 now drives the forked lever 228 toneutral as indicated by the dotted lines in Fig. 20.

In Fig. 18 is shown a detail of the slidable frame arm elements such as54 and 58. rllhe end is bent as at 54X and a plate 54y is bolted theretoas at 258. Between the space included between the parts 54X and 54y ispositioned the tubular member 88 which bears against the roller 260rotatable on the aXlc 259 carried by the parts 54.X and 54Y. Thus theshocker frame elements 58, 54 and 58u may be rolled or shifted so thatthey may drag from selected positions (58, 54' an d 58C) along thetubular member 88 and thus position the shock former with a sidewiseadjustment with respect to the chute elements or so that by shifting thearms 58-54 bundles may be dropped towards the arm 186 or the arm 185 orintermediate the same as may be desired. This is desirable in arrangingthe bundles as they drop from the shock chute 96. Then by the verticaladjustment previously mentioned of the chute itself, a proper control isreceived or whereby the driver of the binder is able from his seat topick the proper place to permit the bundles to drop oil the chute 96.Movement or adjustment of the arms 58 and 54 is controlled by the leverseen in Fig. 16.- Bolted to the lower frame of the binder (is a barmember) 261 supporting the posts 262. A horizontal member 268 slides insupports 264 carried by the posts 262 and leads to a connection on theframe element 265 associated with the elements 58-54. The lever 266pivoted at 267 on the cross member 268K has its keep associated indesired positions upon the are element 268 carried by side supports 269and whereby shifting of the lever to fixed stop positions on member 268moves the lower end 266K and the part 268y so as to move the shockformer arms 185 or 186 Fig. 8 to the ri ght or left as desired. When thesqueezing of the arms 185 and 186 is acconmlished as in Fig. 7 the forks212218 pull the shock backwardly towards the ground spike 179 and theside edges of the arms 185 and 186 as in 'F 15 make an impression in theshocked bundles tending to be maintained even after the release of thearms and forks is accomplished. It will be noted that a brace 282stiifens the sides 210 and 210x as lapped and fastened together.' Thelever 270 pivoted at 271 has a connection 272 iiexibly coupled at 278 tothe shaft 88 for adjustably positioning the paddle roller 89.

The cable 181 Fig. 1 leads over a roller 274 on a` supporti ng bracketrigid to member 241.

The spring 275 connects from the members 148 and 144 Fig. 24 to the post275X Fig. 17 and the rod and spring assembly 160 also eonnects to thepost 27 5".

The chain 276 connects from the clevis 180 to the shaft 187. The length.ofthe chain determines the travel of the clevis and takes the strain offthe other parts.

1n Fig. 10 the deck 277 of the binder is shown for delivering` thebundles to the conveyor 64, as a considerable blow would be struck onthe conveyor 64 at this point by the fall each bundle, we employ thefloor 278 for a distance under the member 68.

As the binder moves forwardly, the lever 266 is used to move the trailersidewise in either direction; rst, for distributing the bundles to theirproper position in the shock former; second, to equalize side draft.lWhen the binder turns a corner, the lever may be moved the properdirection and the latch 279 engages the handle 280 preventing engage`ment of the keeper in any notch on the member 268; this is done justbefore the lever 217 is moved to set the shock. As the shock sets firmon the ground due to its own weight as well as the ground spike, theframe elements 58 and 54 roll at 266 on the shaft 88 since-the keeper281 is disengaged. Thus nothing acts to tip over a shock. On slopingground this lever furnishes a means of properly positioning the trailerto conform to ground positions so as to deposit the bundles at the rightposition in the shock former.

rihe weight of the shocking mechanism is nearly balanced rover thecaster wheel. The elevating mechanism is braced from the binder whilethe trailer has an independent side movement as stated. rThisoscillating side movement of the trailer thus accomplishes several andvaluable features of the invention.

As the jaws 185 and 186 are clamped tight i around the shock the bottomof the bundles are forced to flare out against the member 209-210. Thecenter of the shock strikes the ground a little before the outer edges.rl`he heavy pressure against the jaws 185 and 186 due to the compressedcondition of the enclosed bundles is of assistance in affecting therelease of the aws at the proper-time. During the setting of the shockthe compression of the jaws acts as a shock absorbing device when theshock hits the ground, taking the blow instead of the runners andholding the shock in its oval compacted position during the releasemovement. This heavy pressure so compacts the oval shaped shock thatbinding twine is not necessary around the shock.

lt will be noted that the straight edge board 181 has a slot 288 in itsouter edge which is to pass the ground spike 179 when brought toposition seen in Fig. 8. rlhis board pivots from a suspended positionand is drawn in from behind to stop when it hits the base of the runners257. rlhis board 181 in 8 stands Lat right angles to the direction oftravel of the bundles dropping from the chute 96 and properly aligns thebutts of the bundles; the bundles being somewhat sidewise in thisaligned position compact and settle within the extended. shock formerarms prior to the clamping action. As stated the runners 957 stop theboard when it strikes them, the springs 135 cushion the blow and permitthe arms 131i to go ahead further, the hooks lGQ passing the stops15G-157 and then settling back to an engagement therewith as previouslymentioned.

rEhus the driver of the binder is enabled to dispense with help to shockthe bundles which are properly set up ahead of possible storms. The ovalposition of the shock as given by the preferredv form of the clampingarm elements stated permits an air current to circulate through acentral passage such as is almost sure to occur by this setting of theshock.
